encode_to_plain_matrix

Engine.encode_to_plain_matrix(matrix, level)

Encodes a matrix into a plain matrix format for matrix multiplication.

• Input:
  • matrix: A Python list or numpy array. Data types supported include int, double, and complex double.
  • The matrix should be square, with both dimensions equal to Engine.slot_count.
  • level: optional
    • Specifies the maximum multiplication level for encoding. Lower levels reduce space usage but also reduce the maximum multiplication depth.
• Output:
  • PlainMatrix
